KDL-55X4500 (CH) 2-7
4) Tem p Error (R ED 7 tim es blink )
This indicates high temperature inside chassis. IC1000 on ACW board Side is monitoring
temperature. IC1000 is controlled by BEM I2C.
When it happens;
- Check chassis environment.
- Check around IC1000 and replace ACW board if temperature monitoring circuit has problem.
5) Audio Error (R ED 8 tim es blink )
This indicates Audio Error. (Protection)
It happens;
- Error of Speakers and Harness.
- Digital amp on K2 Board are High Temperature.
Check Voltage at CN1002 20pin on ACW board. ( Low = Normal , High= Error)
If Error , Replace Speaker or Harness or K2 board.
- Low Voltage at IC1800 [ Audio_Vcc(=12V) , A9V , D3.3V ]
- Error of IC1800
Replace ACW board.
.
.
6) FAN Error (R ED 9 tim es blink )
This indicates FAN error. (except 40 inch model)
BE micro pin154 on FBA board detects it.
BE Micro pin154 Normal condition : Low / Error case : High
- Check the harnessconnection of FAN.
- Check the Voltage at CN1301 on ACW board. ( Low = Error , High = Normal)
Replace the FAN.
